Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed April 26,1906. i Serial No. 313,889.

To all whom, it may concern.-

Be it known that 1, WILLIAM ALVERTIN FULLER, a citizen of the United States, residing at Fostoria, in'the county of Seneca and State of Ohio, have invented certain new and useful Improvements in VVire- Working Tools; and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wire-working tools; and one of the principal objects of the same is to provide a tool which will quickly twist the meeting ends of wires of different gages and which will also twist together three strands of wire.

The foregoing objects and advantages are attained by means of the construction illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a tool made in accordance with my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a transverse sectional view on the line 8 3 of Fig. 1. Fig. 4 is a perspective view of one of the wire-cutters.

Referring to the accompanying drawings for a more particular description of my invention, the numeral 1 designates one of the handles of the tool, and 2 is the other handleor member. The handles 1 and 2 are each provided with a circular boss 3, pivoted together by a pintle 4. At a point in front of the pivotal point a pair of jaws are provided for a certain gage of wire. These jaws are provided with outwardly-projecting annular bosses 5, the adjacent faces of the jaws being also provided with semicircular transverse recesses 6 7, which when the jaws are closed conform substantially to the wire to be operated upon. Half-grooves 8 8 are formed in the adjacent faces of the annular portions 5, which when the jaws are closed form wire-receiving apertures at right angles to the half-apertures 6 7 as shown. By this arrangement it will be obvious that if the ends of two wires be laid from opposite sides within the half-groove 7 and the terminals bent laterally and laid, respectively, within the right angled halfgrooves 8 8 and the jaws closed wires will be held from displacement within the completed apetures, formed by the closing of the jaws. Then if the implement be rotated around the wires at right angles to the longitudinal axis, the terminals carried by the apertures connection.

8 8 will be twisted around the main wires, and thus complete the coupling.

At a point back of the pintle 4 the members are also provided with a series of wiretwisting devices, the grooves in which are of varying sizes to accommodate wires of different gages. Each of said devices is provided with oppositely-extending bosses and the longitudinal grooves 8 8.

Wire-cutters 9 are held in dovetailed reoesses in the members 1 and 2, the cutterblades having V-shaped cutting ed es 10 and said cutter-blades being tapere from their cutting edges toward the opposite ends and being seated in dovetailed recesses in the members 1 and 2 of a corresponding contour. The result of this construction is that when a wire is placed between the jaws of the cutter the more pressure applied to the cutters the more firmly the cutters are seated in the recesses. This is owing to the ta ering dovetailed contour of the blades an recesses. The cutters are held in place by means of screws 11.

At the handle ends of the members 1 and 2 a locking device is provided. Said locking device consists of a pivoted cross-lever 12, the cross-head 13 of which is adapted to fit in a recess 14 in the opposite aw. The lever 12 is pivoted at 15, and when the two members are locked together there is no projectionbeyond the surface of the members to catch the clothing or to become unlocked accidentally.

The operation of my-tool may be described as follows: If two strands of wire are to be connected together, the longitudinal strand is passed through the groove or recess 6 7 in that one of the jaws of the proper size to clamp the wire. The wire to be twisted is bent at right angles to the line-wire and placed in the groove 8 at the side of the member 1 or 2. The members are then looked together and the tool -is rotated around the line-wire, after which the projected ends may be severed to make a smooth Where three strands of wire are to be connected, the line-wire is passed in a similar manner through one pair of the jaws, and the two wires to be connected thereto are extended at right angles through the groove 8 at opposite sides of the transverse groove 7 and the wires are twisted together in the manner previously described.

Various changes in the form, proportion,

and the minor details of construction may Y be resorted to without departing from the of, said bosses having halflgrooves in their principle or sacrificing any of the advantages adjacent faces extending at right angles to of this invention as defined by the appended the transverse apertures.
